A detection device and method for studying the impact mechanics of phc pipe piles

Abstract

The invention discloses a detection device and a method for studying the impact mechanics of PHC pipe piles, which relate to the field of pipe piles and include a fixed base, which is rotatably connected to the ground, and a pipe pile body is arranged at the center of the fixed base. The pile body is fixed on the ground, the surface of the fixed base is provided with an outer ring sleeve, and the inside of the outer ring sleeve is provided with an inner ring sleeve. The pipe pile body, the outer ring sleeve and the inner ring sleeve are arranged concentrically. The inner surface of the inner ring is provided with an outer ring guide rail, the inner surface of the inner ring sleeve is provided with an inner ring guide rail, the outer wall of the inner ring sleeve is welded with a connecting plate, and the inner ring sleeve is fixedly connected with the outer ring sleeve through the connecting plate, An impact launcher is arranged between the outer ring guide rail and the inner ring guide rail; the present invention simulates different Azimuth and height can be used for comprehensive data collection for impact studies of pipe piles.

Description

technical field [0001] The invention relates to the field of pipe piles, in particular to a detection device and a method for studying the impact mechanics of PHC pipe piles. Background technique [0002] PHC pipe piles are prestressed high-strength concrete pipe piles. It adopts the pre-tensioned prestressed centrifugal forming process, and after 10 atmospheric pressure (about 1.0Mpa) and steam curing at about 180 ℃, it is made into a hollow cylindrical concrete prefabricated component, with a standard section length of 10m and a diameter of 300mm~ 800mm, concrete strength grade ≥ C80. [0003] In reality, pipe piles may be impacted from different directions and angles, and the impact force will also be partially different, and the impact on pipe piles will also be different. At present, when testing the impact force of PHC pipe piles, The direction of the applied pressure is relatively fixed and single, which cannot simulate this state well, which is not conducive to the...

[0003] In reality, pipe piles may be impacted from different directions and angles, and the impact force will also be partially different, and the impact on pipe piles will also be different. At present, when testing the impact force of PHC pipe piles, The direction of the pressure applied by it is relatively fixed and single, which cannot simulate this state well, which is not conducive to the impact research of pipe piles
